I must agree with the main post. It is aggrevating when you get to a cache, yours or another persons, and it is filled with garbage. I live next to a golf course so guess whats in a lot of the caches???? Golf Balls! It is aggrevating.
Now I also disagree with the talk that the find is the coolest. I am 28 years old and i feel like a kid out there playing in the woods. Every cache is a secret you never know whats in there. U walk through woods, brambles. etc and find a container full of nasty crap.
Then for cool stuff to put in a cache..... anything you would like to find in a container. Do you want to find a stupid golf ball?
